Using the latest version of pip, OscScreenGrabLAN.py fails. Forcing downgrade to 9.0.1 fixes issue, but of course, then you're locked into an old version of the package.

Hi,

The script was working nicely - for PNGs - before the update.

Now I updated to the newest firmware (v00.04.04.00.07) and the script is not working anymore.

I also applied the options to fully upgrade it to a DS1104Z - successfully - and enable all the features.

Here are my results:

$ python OscScreenGrabLAN.py bmp 10.0.1.104
Instrument ID: RIGOL TECHNOLOGIES,DS1104Z,DS1ZA180300357,00.04.04

Python 2 will be shortly deprecated.
Do you intend to port DS1054Z_screen_capture to Python 3 ?
Some people like me, have completely removed Python 2.

For info only - I know this hardware isn't officially supported.
I just tested this code with a Rigol DS2202, firmware 00.03.04.SP2.
Code identifies it as:
Found instrument model 'DS2202' from 'RIGOL TECHNOLOGIES'

PNG capture works.
BMP capture works.
CSV capture seems to always fail after ~1minute, with the following trace:

Traceback (most recent call last):
  File "OscScreenGrabLAN.py", line 198, in <module>
    response = command(tn, ":" + channel + ":DISP?")

I'm personally very happy with just the screen capture functionality, and I hope the word will spread that this is available.

Thanks for your work.

Hi !

I'm trying to get a screenshot of my DS1054Z (04.04.SP1) with your script via my Raspberry Pi (connected with a RJ-45 cable to the scope), but when I execute the command "sudo python2 OscScreenGrabLAN.py 193.168.1.2", the program is stuck in a loop and it's seem to wait an answer according to the log.

The configuration of the Ethernet connection between my devices are correct and I tried to interface with the scope via a telnet client and it was working (*OPC? anwser 1, *IDN? give me information about my scope...). Ping also works.

I've downloaded the release version (1.0.0) and the master and both are giving to me this problem.

Do you have any idea of what is happening ?

Thanks in advance,
Naipsys.

OscScreenGrabLAN.py.log.txt

EDIT : I've tested on my PC under Windows 10, same issues.

I needed to replace it to: tn.write("*idn?\n") # ask for instrument ID
Else it wasn't finding it.

Traceback (most recent call last):
File "OscScreenGrabLAN.py", line 21, in
import Imaging
ImportError: No module named Imaging

replacing it with: from PIL import Image
seems to work, but still give errors later on
This is on gentoo with python 2.7

Hi,

I just installed your software and it worked just fine to capture PNG files.

However, when I try to capture CSV I get the following error messages:

$ python OscScreenGrabLAN.py csv 10.0.1.104

Hi,
This tool really seems to fulfill one of my needs : capture without bloated drivers. However, I can't seem to make it work with my DS1074Z.
Surprisingly, each time I start the same command line, I'm getting a different error message, in sequence:

D:\DS1054Z_screen_capture-master>python OscScreenGrabLAN.py png 192.168.0.212

    % (filename if filename else fp))
IOError: cannot identify image file <StringIO.StringIO instance at 0x02059DA0>

And the cycle restarts if I request again.

It seems the first call cannot see the scope, but wakes it up. The second call sees the scope but it doesn't reply yet. The third call sees the scope, gets a reply (the "Receiving screen capture" step lasts a few seconds) but then crashes.

Any idea ?
